Ripple Tank: Interference of Two Point Sources
 
01:42
A ripple tank is placed above a mirror and a projection screen. Two synchronous point sources, whose frequency can be varied, tap the surface of the water and produce circular waves. The interference pattern of the waves including the lines of nodes can be observed on the screen.

The Original Double Slit Experiment
 
07:40
Light is so common that we rarely think about what it really is. But just over two hundred years ago, a groundbreaking experiment answered the question that had occupied physicists for centuries. Is light made up of waves or particles? The experiment was conducted by Thomas Young and is known as Young's Double Slit Experiment. This famous experiment is actually a simplification of a series of experiments on light conducted by Young. In a completely darkened room, Young allowed a thin beam of sunlight to pass through an aperture on his window and onto two narrow, closely spaced openings (the double slit). This sunlight then cast a shadow onto the wall behind the apparatus. Young found that the light diffracted as it passed through the slits, and then interfered with itself, created a series of light and dark spots. Since the sunlight consists of all colours of the rainbow, these colours were also visible in the projected spots. Young concluded that light consist of waves and not particles since only waves were known to diffract and interfere in exactly the manner that light did in his experiment. The way I have always seen this experiment performed is with a laser and a manufactured double slit but since the experiment was conducted in 1801 I have always thought that it should be possible to recreate the experiment using sunlight and household materials. That is basically what I did here. I will show the interference pattern I observed with my homemade double slit on 2Veritasium but I chose to use a manufactured double slit here to ensure that the pattern was impressive for observers at the beach. Special thanks to Henry, Brady, and Rupert for their cameos, Glen for filming and Josh for helping create the apparatus. Thanks also to the Royal Society for allowing us to view the original manuscript of Young's lecture and the University of Sydney for lending the double slits.

Ripple Tank: Single and Double Slit Diffraction and Interference
 
03:06
A ripple tank is placed above a mirror and a projection screen. A horizontal bar, whose frequency can be varied, taps the surface of the water and produces plane waves. The waves are incident on a barrier containing an adjustable opening. With a narrow single slit opening we see a plane wave emerge as a spherical wave on the other side of the barrier. This can be explained by the Huygens-Fresnel principle which states that each point in the slit forms its own spherical wavefront source. With a wider slit, more point sources arise, causing interference patterns due to the larger angles involved with a broader spatial distribution of these sources.

See the new, higher quality upload. https://youtu.be/4o9TMxXTjOc A 16mm film now incorporated into my article http://www.gcmstudio.com/acoustics/acoustics.html because it's not only relevant to water, but sound and light waves as well. It is from my own collection that clearly demonstrates how 2 sources of vibration interact. Anybody who uses more that 1 speaker to listen to audio should see this, especially engineers. It shows an ideal world, free of reflections (echoes or reverberation) but is educational never the less. Yet, this form of interference is largely ignored, even in texts about acoustics. It has been edited for time but no concepts covered have been removed.

Interference of Waves | Superposition and Interference in light and water waves | Physics

Interference of Waves | Interference and superposition explained in light and water waves with animation | Interference of waves in two dimensions | Physics The phenomena of the light which undergoes refraction and reflection by be explained by the 2 theories of light. They are corpuscular and wave theory of light. But some of the other phenomena such as interference and diffraction can only be explained by wave theory of light. We know that 2 or more wave, motions travel in space at the same time. Sometimes these 2 wave motions combine to and some physical effects take place. Inference is once such physical effect. When 2 or more waves cross each other in the same medium, they both interfere and accident takes. This accident is known as interference of waves. Interference is the combine effect of the disturbance caused by the each individual wave at the same place and at same time. This effect can be understood from the principle of superposition of waves. Principle Of superposition of waves: To understand this concept of the superposition, let's understand some of the examples. When we drop a pin in a tank, we see some circular waves. When other another pin is dropped, we see some more waves. These waves travel in the same tank and some or the other time these superimpose on each other. The resultant wave would have amplitude which is the sum of the displacement due to the individual waves. " The principle of superposition of waves states that when two or more waves travel through the same medium simultaneously, the resultant displacement at any point is the vector sum if the displacement due to the individual waves." In our case the pin is dropped in a ripple tank with 2 pins. If Y1 is the displacement caused at a point due to the first source and Y2 is the displace cause by the 2nd source, then the over displacement R at the point of interference would given by R=Y1+Y2 When both the sources have the same amplitude which then Y1,Y 2 would be equal to Y. When Y1 is due the crest or trough and Y2 is also due a crest or trough the resultant would be the maximum and when Y1 is due to a crest and Y2 is due to a trough or vice versa, the displacement would be minimum. When maximum displacement takes place it's called constructive superposition and when minimum displacement takes place it's called the destructive superposition. In constructive displacement, a maximum displacement curve is produced. Thus, when constructive displacement occurs then the phase difference between the waves would be ZERO or a multiple of 2π. When minimum displacement occurs, wave super impose destructively, the phase difference of the waves would be π or an odd integral multiple of the π. Interference of waves: When superposition of waves occurs, they could be constructive or destructive. This physical effort observed as a result of the superposition of waves is called interference. "The physical effect of the superposition of waves from the sources vibrating with the same frequency and amplitude is called the interference of waves. The physical effect is in the form of vibrations in the amplitude of resultant wave in a given potion of the medium" Interference is a special case of superposition of waves which originate from different sources but have the same amplitude, same frequency.

mini ripple tank
 
03:50
The Mini Ripple Tank is a great way to address the wave-energy standards and to teach about the properties of waves by showing how water waves behave. Ripple tank wave generators are such a wonderful way to demonstrate the principles of wave propagation, reflection, refraction, diffraction and interference, but they can be time consuming to set up and take down. This Mini Ripple Tank addresses these issues by providing a completely self contained device, requiring no set-up apart from the addition of water. Easy changing of wave frequency! Excellent for showing diffraction, 2 source interference patterns, refraction, and reflection. Great for small groups! It is small and portable, making it great for small group demonstrations or stations. http://www.arborsci.com/mini-ripple-tank
